Thermocouple probe

Check to be sure that the thermocouple is securely

 

 

connected to the oven control. If the thermocouple is

 

 

connected to the oven control, and the control

 

 

indicates “LP FAIL” or “RP FAIL”, disconnect the

 

 

thermocouple from the oven control and measure the

 

 

resistance of the thermocouple. The left thermocouple

 

 

should read approx. 21Ω. The right thermocouple

 

 

should read approx. 11Ω. If these readings are not

 

 

achieved, replace the thermocouple. If these readings

 

 

are correct, proceed.

 

Oven control

If the thermocouple checks good, but the oven control

 

 

display indicates that there is a thermocouple failure,

 

 

replace the oven control. If the oven control indicates

 

 

a temperature reading but the oven will not heat,

 

 

proceed.

 

 

Thermocouple

WITH POWER ON AND THERMOCOUPLE

 

 

ATTACHED TO THE OVEN CONTROL: Measure the

 

 

DC millivolt output of the thermocouple. Refer to the

 

 

thermocouple chart (located in the “Removal” section

 

 

of the manual) for proper millivolt readings. If these

 

 

readings are not achieved, replace thermocouple.

 

Oven control

If the thermocouple checks good, but there is no

 

 

voltage output to the temperature regulation valve,

 

 

replace the oven control. If there is voltage output to

 

 

the heat relay, proceed.

 

Oven air pressure switch

Check for supply voltage at the air pressure switch, if

 

 

no voltage is present, trace wiring back to the oven

 

 

control. Check for supply voltage on both sides of

 

 

switch. If voltage is present on one side only, check

 

 

for air tube blockage. Adjust air pressure switch. If the

 

 

above fails, replace air pressure switch.

 

Heat relay

Check for line voltage supplied to the coil of the heat

 

 

relay. If no voltage is present, trace wiring back to the

 

 

air pressure switch. If voltage is present, check to be

 

 

certain that all of the contacts are closing when the

 

 

relay is energized.. Also check for opens or shorts in

 

 

the operating coil. Replace temperature regulation

 

 

valve as needed.

 

 

Heating elements

Check the Amp draw on each power lead for proper

 

 

load. Check the specification plate for proper rating

 

 

information.

 

 

 

If the Amp draw is high or low, check the individual

 

 

heating elements for opens, shorts and proper

 

 

resistance.

 

 

 

To check the resistance of the elements,

 

 

TURN OFF THE POWER!

 

 

Remove all wiring from the heating elements and use

 

 

an accurate digital meter.

 

 

The element resistance should be as follows:

 

 

220V – 29 ohms

approx.

 

 

230V – 32 ohms

approx.

 

 

240V – 34 ohms

approx.

 

 

If all readings are not correct, replace heating

 

 

elements as needed.
